Subject [jira] Updated: (DERBY-4066) Allow functions/procedures to take Blob/Clob arguments

Rick Hillegas updated DERBY-4066:
---------------------------------

    Attachment: derby-4066-01-ab-enableLobArgs.diff

Thanks for the quick feedback, Bryan and Kathey. Attaching a second rev of the patch: derby-4066-01-ab-enableLobArgs.diff.
This changes the canon for the LOB test, which used to expect the old failure. I also incorporated
Kathey's recommendation to change the test to run client/server as well as embedded. This
turned up another problem: in the client/server configuration the numeric/decimal tests in
AnsiSignaturesTest raise an overflow condition. I think this is a bug and I will log an issue
to track it. In the meantime, I have disabled those tests for the client/server configuration.

In addition, the XMLTypeAndOpsTest had errors because the original patch allowed XML datatypes
as method parameters too. That situation should still be forbidden until we provide an implementation
of JDBC's SQLXML datatype. This second patch disallows XML datatypes as method parameters.


Touches the following additional files:

M      java/testing/org/apache/derbyTesting/functionTests/tests/lang/LOB.sql
M      java/testing/org/apache/derbyTesting/functionTests/master/LOB.out

I will run the regression tests again.

> Derby objects if you try to declare a function or procedure with an argument whose type
is BLOB or CLOB. These kinds of arguments are allowed in the SQL standard and the matching
Java types are java.sql.Blob and java.sql.Clob. See the SignatureMatching.html summary attached
to DERBY-3652.
> We should lift this restriction and allow functions and procedures to take large object
arguments.
